Long time ago, the Egyptians figured out that a triangle with sides of length **3**, **4** and **5** had a right angle as its largest angle. You must determine if other triangles have a similar property.

#### Input

Consists of several test cases, followed by a line containing **0 0 0**. Each test case has three positive integers, less than **30000**, denoting the lengths of the sides of a triangle.

#### Output

For each test case print a line containing "**right**" if the triangle is a right triangle, and a line containing "**wrong**" if the triangle is not a right triangle.
